Unless your doctor says something I wouldn't worry. My first consistently measured a week behind and was born 2 weeks early at 7 lbs 5 oz. so ultrasound measurements aren't always the most accurate! Also I never really thought to look at the size of the placenta! My first was anterior and I don't have any problems aside from rarely feeling movement. But the placenta at this point I think will just look large because the baby is still fairly small. I would try not to worry until you get your results.

I wouldn't worry about the baby measuring a week behind, they say the further into our pregnancies we get, the more the sizing varies from our estimated due date. Did you get an early ultrasound that dated you? not based on LMP but on the size of the baby initially? like 7-8 weeks? I heard tha'ts the most accurate they go by.

I don't know why I included the week difference. I'm not concerned about that. Lol. But yes, she's been a week behind from the beginning even though I know exactly when she was conceived. However, I did get a little baby making lesson and learned that sperm can stay inside up to 72 hours before meeting the egg! And that's probably what happened.
